AUTOMOBILE HEADLIGHT AND CONTROL THEREFOR.

Application filed December 15, 1921, Ser1al No. 522,725. Renewed June 18, 1927.

My invention relates to headlights for motor driven vehicles and its principal object resides in providing in a headlight of the type generally .used on automobiles, means adapted 'to prevent the emission of upwardly directed light rays without dimin ishing the eiliciency'of the device.

A further object resides In, providing a simple adjustment by which the driver of the vehicle may'changethe direction of the P light beam emitted from the headlight, in

order to illuminate the road at the desired distance. ahead of the vehicle, on inclines as 'well as on a level ground,,and still another aim of the invention is "to provide a head- 1 light of high illuminative power, in which the source of light is concealed soas to be invisible at the front of the same. By the use of my invention, the glare produced by the direct or primary light rays issuing from the lamp of the headlight through the glass covered front thereof and the reflected or secondary rays which emerge from the parabolic reflector, is complete y eliminated with the result' th'at accidents frequently occurring by'the blinding effect of the glare on pedestrians and drivers of approaching vehicles, is avoided.

With the above and other objects in view, my inventionresidesin the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described with reference to the accompanying drawings in the several views of which like parts are similarly designated and inwhich v Figure 1 is a side elevation of an automobile equip ed with the device;

Referring to the drawings, 1 desi ates a lamp casing the front\of.whi ch is c osed b a plate 2 of opaque material, provided wit and 5, j formed one The lower opening which is much smaller fiian the other, is closed by a glass panel 7 and it is, interior] of the casing covered by, a housing 6 which has a reflective inner through the lens panel 4 carriedby the lens support 4*.-

The hereinbefore mentioned lamp 10 is mounted in a socket 9 on abase 8 in the bottom portion of the casing, and placed imme- 1,654,696, PATENT OFFICE.

assing directly through the opening 3 ordiately above the lamp and axially in aline- 1menttherewith and immediately adjacent the rearedge of the adjacent'portion of the web ,3. is an open-ended tube 12 which by means of a bracket 11 is rigidly fastened to the casing. The tube is interiorly screw- ,threaded for 'the' adjustable support of the circular frame 13' of a condensing lens 14."

Mounted above the tube 12 and opposite to the opening 3, in the front of the casing,

is a slanting reflectorpreferably composed of a mirror 16 set in a frame 15. The tube 12 occupies the greater part of the space be tween the web 3* at the lower portion thereof, and the wall of the casing'so that the maority of the light rays emanating from the lamp pass through the tube into the upper portion ofthe casing'and onto the slanting mirror which reflects the rays in a forward and downward direction through theopen- 3 in the front of'thecasing,

t w1l l' be evident that owing to the slantlug-position of the mirror no'rays oflight passing through the Op ning 3 are reflected m an upward direction and the entire light beam produced in the operation of the lamp, is directed toward the road ahead of the vehicle to which the lam is applied.-

.The lens 14 in the tube Focuses the light onto the mirror n a beamof restricted area,

and any light rays passing. f the m exteriorly of the tube. are prevented froiii passing --u wardly throu h the. o enin 3 yth weiii3 g g 1 e casing 1 has a recessed hemi-spherical head18 which in practice is supported upon and secured to the porrespondingly shaped end of a correspondingly recessed bracket 23 whichisjfixed at automobile as shown in Figu It preferred m the front of the unti lea 0 the headlights so, that may rotate in con junction with a part of the steering'gear of the vehicle in order a constantly throw its light beam in the direction inwhich thevehicle travels, and to accomplishth'is 'movement, roller-bearings are provided as shown at19 in Figure 3, and a shaft 20 on'the head of the casing-extending through the end of the bracket, is connected with a suitable. mechanism such as the -.pinion'21, the rack.

bar 27 slidable in a passage 28 the bellcrank 29 and the rod 30, shown in fiigure 5, to effeet the rotation of the headlight by-movement of the steering 'post 31.

Inasmuch as the present ap llcation' is restricted to the construction 0 the headlight per se no further explanationof its w dirigible features is required.

- In order to change the direction of the lightbeam emitted through the opening 3 the headli ht according ;to the degree of inclination o the road ahead of the automobile, the frame of the mirror 16 is pivotally mounted at its upper end and its 0pposite end is connected with a mechanism by 'means of which the angle of inclination of the reflector can be varied by an occupant of the drivers seat .of the vehicle. The mechanism above referred to com- 30 prises a link 17 longitudinally slotted as at 18, and-pivotally attached at. the lower end of the frame 15 0f the mirr0r'16. A' shaft '32 rotatably mounted in a bore of the horizontal bracket arm 23, has a laterally projectin arm 35 which' l oosely engages in the slot 01% the link 17 sothat by a partial rota- I tion of the shaft, the link may be raised or' r lowered and therebymove the mirror frame about its pivotal axis.

ters Patent is:

The two shafts extending through the bracket arms of the two headlights are axially alined and they are connected by aicoupling 32* shown in'- Figures 4 and 5, which 1 has a crank. arm in connection with an operating rod 34 extendingjrearwardly .ofthe V shafts within easy reach of the driver of the vehicle.

It will be apparent thatthe rod 34 must be positioned. at one side; of the vehicle in order toplace its end in adjacency to the drivers seat and that in consequence the shafts- 32 of the two'headlights are-0 unequal lengths. 7

What I claim and desire to secure by Let- In a headlight, a'casing including a front cover having an opening-in the upper portionther'eof and a lens support positioned within the-casing in opposition .to theopening and diverging inwardly from the'casing toward the lower edge of the opening, the casing cover having a web connectin the lens support and cover at the sides an bot norm MONTGOMERY.
